Let me see your bookshelf Q580R is a quenched and tempered high-strength steel plate for pressure equipment, and its grade is composed of the initial letter "Q" in Chinese pinyin representing the yield strength of "yield", the specified minimum yield strength value of 580, and the initial letter "R" in Chinese pinyin of the word "Rong" in the pressure vessel. The steel plate is implemented according to GB T7136-2023, which stipulates its brand indication method, order content, size, shape, weight, technical requirements, test methods, inspection rules, packaging, marks and quality certificates, etc. The thickness range of the Q580R is 10 120mm.

The delivery state of Q580R steel plate is quenched and tempered heat treatment state of quenching and tempering, in which the tempering temperature is not less than 600. In addition, its manufacturing method should be in accordance with GB T7131 and should be vacuum-processed. The compression ratio of continuous casting billet and steel ingot is not less than 3, and the compression ratio of electroslag remelting billet is not less than 2.

The general requirements of the mechanical properties and process properties of Q580R steel plate should meet GB T7131, while also meeting specific performance indicators. For steel plates with a thickness greater than 36mm, a group of impact samples can be added at the thickness 1 2, and the impact absorption energy index is determined by the supply and demand parties through negotiation. In addition, if the demander requires, the steel plate with a thickness greater than 36mm can also be tested for drop weight, and the drop weight test method should be carried out in accordance with the provisions of GB T6803.

In terms of surface quality, the surface quality of Q580R steel plate should be in line with GB T7131. At the same time, its ultrasonic testing according to NB T470133. Implementation, the qualification level should not be lower than the level. If there are special requirements, they should be indicated in the contract.

Q580R steel plate has a wide range of applications in many fields due to its excellent strength and corrosion resistance. In aircraft construction, it is an ideal material choice. At the same time, it can also be used to make structural materials for vehicles such as ships and railway vehicles. In the energy industry, the Q580R is widely used in the construction of oil and gas extraction equipment and nuclear power plant facilities.
